Basalt formations off the East Coast of the U.S. could suck up a billion tons of carbon dioxide, according to a new study. Paleontologist Paul Olsen, of Columbia University's Lamont-Doherty Earth Observatory, explains how to get the CO2 into the rock...s, and why scientists believe it won't leak out.[more]

Igneous rock forms from melted rock called magma. Magma exists inside the earth's surface, and it becomes lava when it is released through a volcanic eruption. When it cools, it becomes igneous rock.

Granite is a type of igneous rock that is very abundant and found all over the world, and the three main minerals of granite are quartz, padgoclez and potassium feldspar.

Igneous rocks are rocks derived from the cooling of magma, molten material originating from the upper Mantle/lower crust. Igneous rocks are classified by their texture and their composition. Rocks' textures range from fine-grained (extrusive/volcanic...) or coarse-grained (intrusive/plutonic). Compositions range from silica-rich (felsic) to silica-poor (mafic). (05:57)[more]

Igneous rocks are one of the three main classifications of rocks, and they are formed both above and below ground. Learn about the intrusive and coarse-grained nature of igneous rocks with help from a lab manager and research scientist in this brief ...video on identifying rocks. Run time 0:54.[more]

The third classification of rocks are those which were formed deep in the earth's crust by melting and then recrystallization. These rocks include volcanic rocks, igneous rocks of dykes and sills and plutonic rocks such as granite, syenite, gabbro an...d ultramafic rocks. Many specimens are discussed that are not often found in classroom labs or textbooks. This is an excerpt from this fascinating and informative video from TMW Media.[more]
